Bernard Madoff arrested over alleged $50 billion fraud

Bernard Madoff, a quiet force on Wall Street for decades, was arrested and charged on Thursday with allegedly running a $50 billion "Ponzi scheme" in what may rank among the biggest fraud cases ever. The former chairman of the Nasdaq Stock Market is best known as the founder of Bernard L. Madoff Investment Securities LLC, the closely-held market-making firm he launched in 1960. But he also ran a hedge fund that U.S. prosecutors said racked up $50 billion of fraudulent losses. Madoff told senior employees of his firm on Wednesday that "it's all just one big lie" and that it was "basically, a giant Ponzi scheme," with estimated investor losses of about $50 billion, according to the U.S. Attorney's criminal complaint against him.
